ATTACHMENT TO GRAIN-SEPARATORS.

Specification of Letters Patent.

Patented Oct. 17, 1916.

Application filed December 23, 1915. Serial No. 68,367.

To all whom it may concern Be it known that I, MALGUM SoLoMoN J o- SEPH MoMURAoHY, of the town of Strathclair, in the Province of Manitoba, Canada, have invented certain new and useful Improvements in Attachments to Grain-Separators, of which the following is the specification.

The invention relates to improvements in attachments to grain separators and particularly directed to the bundle carrier of a separator, and the object of the invention is to provide an oscillating divisional board in A still further object of the invention, and

one resultant of the insertion of the oscillating divisional board, is to allow a single pitcher to feed the carrier evenly at both sides, and while remaining at one side of the bundle carrier.

With the above objects in view the invention consists essentially. in the arrangement and construction of parts hereinafter more particularly described and later pointed out in the appended claims, reference being had to the accompanying drawings in which;

Figure 1 represents a side View of the bundle carrier supplied with my invention. Fig.

2 represents a plan view of the same. Fig. 3 represents a back view of the pulleys and adjacent parts mounted on the front end of the separator. Fig. 4 is an enlarged detailed vertical sectional view through the, frontend of the bundle carrier. Fig. 5 is an enlarged detailed vertical sectional view through the front end of the bundle carrier, the section passing through the same directly in advance of the front end of the divisional board. Fig. 6 represents a vertical sectional view through the adjustable bearing provided for the upper pulley shaft.

In the drawings like characters of referin respect to the other.

ence indicate corresponding parts in each figure.

1 represents the front end of a separating machine, presenting, as is customary, the crank shaft 2, the cranks of which carry the band cutter knives 3. The crank shaft is driven in the ordinary way by a drive pulley 4 operated by a belt 5, which latter belt is driven by a traction engine (not shown).

6 represents the bundle carrier which is provided with an endless conveyor 7 designed to deliver sheaves placed on the bundle carrier to the band cutting knives.

All the above parts are of ordinary construction and form no part of my invention, so the details thereof are not herein further enlarged upon.

Centrally within the carrier andeXtending longitudinally thereof I provide an oscillating divisional board 8 which is permanently fastened in any suitable way, such as by straps 9 and 10, to a longitudinally disposed tubular shaft 11 located directly above the conveyor and having the forward end thereof carried by a pair of cross beams 12 and 13 extending between the sides of the carrier. A head strip 8 is fastened to the top edge of the divisional board. As will be observed, the beam 12 is elevated to clear the forward end of the conveyer, and in order to prevent sheaves from being thrown onto the carrier in advance of the beam 12, I have connected the top edges of the beams with suitably disposed slats 14. I wish here to point out that this divisional board is not supported at the rear end, being wholly held in its position by bearings located at the front end of the carrier. This is an important feature in connection with this board.

On top of the front end of the separator I mount a pair of standards 15 and 16 which carry lower bearings 17 and 18 for a lower pulley shaft 19 on which I have mounted a series of pulleys 20 graduated in size.

21 and 22 are adjustable top bearings slidably mounted in the standards and carrying a top pulley shaft 23 on which I have mounted a series of pulleys 24 graduated in size. The top pulleys and the bottom pulleys are arranged in respect to one another so that one can, by changing the belt 25, have various driving speeds of theone shaft Spiral springs 26 are inserted between the top and lower bearings, which normally hold the bearings up, and .the top bearings are rendered adjustable by the provision of adjusting screws 27 fitted with cranks 28 and connected to the bearings.

The lower pulley shaft 19 is fitted with a bevel pinion 29 which is continuously in mesh with a driving bevel pinion 30 mounted on a counter shaft 31 carried by suitable bearings 32 and 33 located on a base plate 34 attached to the top of the separator. The pulley shaft 23 is provided with a driving pulley 35 which is connected by means of a belt 36 with a pulley 37 secured to the crank shaft 2.

According to the above arrangement it is obvious that when the crank shaft is driven, the counter shaft 31 will be turned fast or slow, dependent on the adjustment given the belt 25 on the pulleys.

The rear end of the counter shaft 31 has permanently secured thereto a downwardly extending lever 38' fitted with a series of adjusting holes 39, and to the lever I have attached pivotally a cross bar 40 by means of an adjusting screw 41, the screws being provided so that the bar can be adjusted on the lever toward or away from the center of the counter shaft. The bar 40 is connected with the forward end of the divisional board in a manner such that as the counter shaft r0- tates the divisional board will be oscillated or rocked laterally in the carrier. In the present instance I have provided the following connections between the board and tie bar: The lever 36 is fast to the shaft 31 and rotates with it. This lever carries the cross bar 40 which is adjustably and pivotally fastened to the lever so that its position can be changed in respect to the shaft 31 and also that in any of the positions in which it is adjusted it can rock or turn on the adjusting screw 41 which pivotally holds it to the shaft effects through the bar, the pulling of the chains in a manner to produce an oscillating movement in the divisional board. and 43 are cables located at opposite sides of the carrier and guided by inserted pulleys M and 4-5 attached to the sides ofthe separator. The forward ends of these cables are provided with chains 46 and 47 which pass over suitably located pulleys 418 and have their inner ends fitted with hooks 49 and 50 secured to eyes 51 and 52 extending from the opposite sides of the divisional boa-rd. The rear ends of the cables are supplied with chains 53 and 54 passed over suitably located pulleys 55 and 56 and connected by means of hooks 57 and so that the divisional board can be properly centered and the springs take up the jar of a falling sheaf on the divisional board.

61 is an upstanding arm permanently secured to the forward end of the tubular shaft 11 and having the upper end thereof provided with a spiral spring 62 which is connected to a suitable hook 63 located at the front side of the beam 12. This spring is also utilized to prevent the sheaf pitched. against the divisional board from jarring the chains.

In order to better understand the invention I will now describe the manner in which it operates when the separator is running, and assuming that sheaves are being pitched by pitchers located at both sides of the carrier and that an adjustment has been made such that the divisional board swings well over, such as indicated in Fig. 5, when the parts are operating. With this arrangement it is obvious that the pitchers will have to throw the sheaves alternately, each one putting a sheaf in his side of the carrier when the divisional board has swung far enough to the side to allow his sheaf to drop on the carrier. If reference be here made to Fig. 5 of the drawings, it will be seenthat when the divisional board is in the position as shown in dotted outline, the pitcher on the right of the carrier can throw a sheaf into the conveyer while the one on the left cannot. The result of this is that the sheaves are fed evenly by the conveyer to the band cutter knives alternately at both sides. This is not the case where a permanent, vertically upstanding divisional board is installed, as with such it is possible for both the pitchers to throw at the same time with the result that there is a heavy feed to the knives for a short interval and then no feed at all. With my attachment there has to be a continuous feed and at no time an over-feed. A further advantage gained by this oscillating board is thata single pitcher, at one side of the carrier, can feed a separator properly. This is done in the following way :VVhen the board swings away from him he throws the sheaf into the near side and as the board swings toward him he throws the sheaf into the far side. In connection with this latter throwing it is pointed out that it is an easy matter for the pitcher to pitch the sheaf onto the far side of the conveyer, as at the time of pitching the divisional board is well inclined toward him; Such is not the case where a vertically disposed, permanent board is used, as owing to the vertical position of the board it is difficult to throw over it.

By. providing ,the adjustable speed, as arranged for in the pulleys and belt, the amount of feed can be controlled directly words, thereisa heavy crop the speed is slowed down through the belt so that the board oscillates slowly. With a light crop the device is speeded up to make the board oscillate quicker. According to the rate at which the board oscillates, so is the feed, and consequently it is possible to govern the whole operation absolutely in conformity with the crop conditions.

Then one desires to fold up the carrier, as is customarily done, it is only necessary to release the spring 62 to free the crank 61 and to undo the hooks 49 and 50 from the eyes 51 and 52. This permits the divisional board to be swung down onto the conveyer and entirely out of the road. It is not necessary to take out the divisional board as occurs at the present time where a permanent, upstanding divisional board is used.

What I claim as my invention is;

1. A grain separator including a conveyer, a conveyer support, and a laterally oscillating divisional board within the support and above the conveyer.
